I am in the same boat, my current OS is linux 7.9 and gitlab version is gitlab-ce:14.2.7-ce.0. what steps did you follow to upgrade to latest? I tried doing a backup at OL7 vm and restoring on new OL8 vm with same gitlab version, but failing on postgresql and redis, and not able to bring up the container at all.
There is no such thing as linux 7.9, so it’s not.
Technically only the kernel (which is quite irrelevant in this context) is called linux, but the most recent version is 6..
7.9 might be the version of CentOS you’re using - that is what this thread was about.
But on to your problem:
You need to give more details on how it’s failing if anybody is to have any chance of helping you.
